July 19, 1 949. E. E. JACOB BED SPRING-SUPPORT Filed Oct 2, 1946 INVENTOR; Edwanz/ ,Z', 3602 Patented July 19, 1949 UNITED STAT T OFFICE 8 Claims. 1

This invention relates to means for converting a bed spring into a bed and in particular relates to individual leg supports adapted to be secured in fixed position to the bed spring so as to elevate the same and provide abed.

An object of the present invention is to provide supporting legs adapted to be easily installed beneath a bed spring or coil spring mattress and attached to the marginal base frame thereof, whereby the bed spring may be readily and inexpensively converted into a bed without necessitating the use ,of conventional bulky and heavy bed frames which are diilicult to handle and usually require considerable time and effort to assemble and knock down.

A further object of the invention is to provide a simple, economical and sturdy means for converting any conventional coil spring mattress or bed spring into a bed such, for example, as a studio couch, Hollywood bed or day bed, said means comprising .a number of leg members adapted to be arranged conveniently and at suitable points beneath the marginal angle frame of the bed spring and rigidly secured thereto by means of clamping devices on the upper ends of the leg members cooperable with the frame of the bed spring.

Another object of the invention is to provide individual leg supports for a bed spring having improved and novel clamping devices capable of permitting easy installation of the leg supports beneath the frame of the bed spring at any desired points along the sides thereof. The improved construction is such that the bed spring with the leg supports installed thereon becomes a conveniently useable and relatively light bed structure, easily handled and moved about, and which may be quickly knocked down when not in use with the leg supports capable of being detached and stored in a minimum of space.

Other objects of this invention will appear in the following description and appended claims, reference being had to the accompanying drawings forming a part of this specification wherein like reference characters designate corresponding parts in the several views.

Fig. 4 is a perspective view of one of the legs carrying clamping means for clamping the leg in fixed position to the bed spring frame.

Before explaining in detail the present inven tion it is to be understood that the invention is not limited in its application to the details of construction and arrangement of parts illustrated in the accompanying drawings, since the invention is capable of other embodiments and of being practiced or carried out in various ways. Also it is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation.

In the drawings I have illustrated, by way of example, one embodiment of the invention in which a conventional bed spring In is adapted to be supported in an elevated position by means of individual leg supports which carry clamping devices at their upper ends by means of which the bed spring may beconverted into a'bed. The bed spring or spring mattress H3 which, in accordance with the invention, is to be supported in desired position above the floor, may be of any conventional type, such as the open coil spring structure illustrated in Fig. 1. This particular spring or spring mattress til comprises the usual individual coil'springs II connected around the upper edge of the structure by means of the usual framing or border wire l2. The coil springs in the type of spring mattress shown in Fig. 1 are mounted on interconnected transverse and longitudinally extending strips in the usual manner which at their ends are attached to the bottom rectangular frame of the bed spring. This frame may be of angle. iron construction comprising spaced longitudinal members I3 and transverse end members 54.

As illustrated in Fig. l, the bed spring in is supported along each side thereof by means of three longitudinally spaced supporting units or leg supports which are identical in construction and generally indicated at l5. Each leg support it comprises a leg member to which may be formed either of wood or metal and which carries at its upper end a clamping device by means of which the leg support may be readily and conveniently attached at the desired, locality to one of the side rails or frame members 13 of the spring mattress structure.

7 Each clamping device in the present instance comprises a channel shaped metallic clamp support I? which embraces the upper inner corner of the leg to and accordingly comprises a top horizontal web .lla resting upon the upper nd of the leg, a vertical web I'lb which extends along the inner side of the leg, and integral spaced side flanges He which engage opposite sides of the leg. Thus, the clamp support l1 in each instance engages the upper end of the associated leg it and embraces three vertical sides thereof thereby providing a means for holding the leg firmly in position. The opposite side flanges llc of the clamp support are secured at their upper ends to the leg i6 by means of screws 18, and the lower ends of these flanges are secured to the leg by means of screws 19 having their shanks extending through curved slots 20 in the flanges. The slots 20 in the side flanges of each clamp support have their centers of curvature at the longitudinal axis of the screws l8 whereby, upon loosening the screws IS, the clamp support may be adjusted a limited distance angularly about the axis of the screws It so as to vary the angular relation of the leg IE to the clamp support.

The clamping device for each leg comprises a vertically extending clamping member 2l which is swivelled or pivoted at its lower end to the support 11 by means of a bolt or screw 22 threaded into a screw boss 23 formed on the flange Nb of the clamp support. The upper end of the clamping member 2i is bent inwardly and upwardly to provide an angularly extending portion 21a which is provided with an open-ended slot 2s adapted to receive the shank of a bolt 25. When the bolt is in assembled relation to the clamping member 2|, as shown in Fig. 2, the head 25a, of the bolt engages the lower face of the inclined portion 2la.

The clamping device for each leg also comprises an upper horizontal clamping member 26 which terminates at its inner end in an upwardly and inwardly extending bent portion 260; which is adapted to extend in opposed parallel relation to the angular portion 2 id of the clamping memher 2!. The portion 26a has a hole to receive the shank of the bolt 25, and threaded onto the upper end of the latter is a wing nut 21. The outer end of the clamping member 26 terminates in a return bent portion 2% which preferably extends integrally from the outer edge of the top. web Ila of the clamp support.

When it is desired to assemble the leg support in supporting relation to the side rail l3 of the bed spring the wing nut 21 is loosened so as to loosen the bolt 25 in the slot 24, whereupon the vertical clamping member 2| is swung laterally and downwardly about its pivotal connection 22 to the position shown in dotted lines in Fig. 3. The bolt is then shifted upwardly to position the head 2 a thereof proximate to the bent portion Eta of the upper clamping member. The leg support may then be shifted inwardly and assembled on the rail I3 with the flange [3a, of the rail positioned against the inner side of the clamp support and the upper flange ll 3b of the rail laying within the space between the clamping member 25 and the top web Ila of the clamp support, as shown in Fig. 2. When the leg support is thus assembled with the rail l3 of the bed spring the clamping member 2| is swung upwardly from its dotted line position in Fig. 3 to its full line position, causing the shank of the bolt 25 to mesh in the slot 24. The wing nut may then be drawn down on the threaded shank of the bolt to draw the clamp portions 2 la and 26a together, thereby causing the horizontal and vertical portions of the clamping members to grip tightly the flanges of the rail 13. In the event, after attaching all six legs to the frame members or rails l3 of the bed spring, any of the legs do not stand straight in a vertical direction due to any irregularity of the angle iron frame l3 or for any other reason, then it is merely necessary to loosen the screws l9 and straighten the leg into proper position. This angular adjustment of each of the legs is permitted, as previously described, by reason of the adjusting slot 20. Upon adjustment of the leg the screws 1 9 are tightened so as to maintain the clamp support 11 in rigid position with respect to the leg.
